As a doctor, Grinspoon was the first American physician to prescribe lithium carbonate for bipolar disorders. He also founded the Harvard Mental Health Letter, and was its editor for fifteen years.

Grinspoon originally endeavored to write Marijuana Reconsidered in order to build a case against marijuana, but as his research progressed, he realized the complexities of the plant and was moved to advocate for legalization. He has testified before Congress, and as an expert witness in various legal proceedings, including the deportation hearings of John Lennon. Grinspoon worked with Ramsey Clark on a number of international marijuana related incidents.

Grinspoon was a prominent speaker at the 1998 NORML conference in Washington, DC.

Dr. Grinspoon runs 2 websites: 1) Marijuana: The Forbidden Medicine[1] that includes thousands of individual anecdotes concerning the medical uses of marijuana as well as Q&A; and 2) Uses of Marijuana[2] that allows for people to submit essays relating to the 'enhancing' effects that marijuana can have on the user. The focus is on effects which are meaningful for the individual: not merely 'increased appetite', but rather effects such as increased creativity, rushes of insight/new ideas, or increased appreciation for music, art and nature.

Grinspoon appeared in an episode of the Showtime series Penn & Teller: Bullshit!. The episode, which addressed America's War on Drugs, aired in the show's second season. Grinspoon discussed the way marijuana helped his young son while he was dying from leukemia in the 1970s, completely eliminating the horrible nausea & vomiting he experienced after each of his chemotherapy treatments and, thereby, making the final year and a half of the boy's life far more comfortable, for his son, and for Grinspoon and his wife by not having to endure the pain of witnessing their son suffer.
